ABOUT BIOACCUMALATION

Friday, November 5, 2010 @ 12:50 AM

THIS WOULD BE A MORE DETAILED SUMMARY ON THE BIOACCUMALATION :D

As you can see in the picture, methylmercury then enters the food chain when it is absorbed by plankton species

plankton are eaten by its consumers, which then are eaten by larger and larger fish.

Methylmercury accumulates in the tissues of fish and shellfish via a process called biomagnification, through which methylmercury concentration increases as it moves up from one ''level'' to the next.

Thus, smaller fish that are lower down in the food chain have lower concentrations of mercury in their tissues while larger fish that are higher up in the food chain have higher concentrations.

For example, sardines contain about 0.01 ''unit'' of mercury while sharks contain from 1''unit'' to as much as 4 ''units''.
